GPI M30 Mechanical Fuel Meter in Liters For Sale

I bought the wrong meters (liters instead of gallons), and had them installed on customer tanks for a couple months before noticing.
They all came new showing 100 liter total (probably calibration from the factory). One was installed on a gas pump, but never had anything pumped through it. The other two were installed on farm diesel pumps; one had 184 liters pumped through it (for a total now of 284), the other had 712 liters pumped through it (for a total now of 812).
These are like new, just slightly used. The boxes I will ship them in are marked as the gallon meter variant, but the meters inside are in liters. They are sold new for $260 each.
